Title: Improvements in or relating to apparatus for measuring and delivering liquids
IPC: B67D7/16
Filed: 1929-10-22
Abstract: 340,668. Delivering and indicating measured quantities of liquid. SOC. INDUSTRIELLE D'ARTICLES D'ECLAIRAGE, 15, Boulevard Richard Lenoir, Paris. Oct. 22, 1929, No. 32074. Convention date, Oct. 23, 1928. [Class 106 (v).] Fixed-chamber apparatus.--Liquid is supplied by a pump 1 to an overhead tank 5 and thence to a container 16. It is retained to the level of the overflow pipe 23, and the amount to be delivered then displaced by a plunger 9. The shell 29 of the controlling valve 15 is rotated from the pump shaft by chain 2a and sprockets 52, 53, worm and wheel 45, 46 and shaft 41. The plunger 9 is raised by a cable 8 connected to a lever 51a having a roller 51 which cooperates with a cam 50 on a shaft 49 driven from the sprocket shaft 47. Ports in the valve shell 29 successively open the chamber 16 to supply from the tank 5, permit levelling to the top of the pipe 23 by connection to the drain pipe 25, and the discharge of the displaced liquid by way of the pipe 27. Completion of levelling and discharge before the beginning of the next operation in the cycle are ensured by placing a slipping ball-clutch 58 in the valve-shell drive, and the insertion of pressure-responsive devices 67, 79. Catches controlled by these devices engage recesses in the disc 59 and its boss and stop rotation of the shaft 41 until the necessary step has been completed. By providing an enlargement or reservoir in the union of the delivery hose with the pipe 28 continuous discharge may be obtained without cessation of pumping. The enlargement may have transparent panels. With registering mechanism.-Dialling mechanism for restricting delivery to a predetermined number of units is operated from the shaft 49 of the cam 50. When delivery is completed a spring-controlled rod 88 snaps into notches 87, 92 on discs 86, 93 secured to the shaft 49 and dial 94 respectively. A second dial 95 is normally pressed against a friction disc 95a, and the latter. against the dial 94, by a shoulder 100. The front disc 95 is cut away sufficiently for the indications of the disc 94 to be seen through a window 96, while those of the disc 94 are visible through window 97. At the conclusion of delivery the disc 94 indication has been brought back to " zero," while the front disc has been rotated until the number of units delivered is displayed through the lower opening. By pulling the knob 102, the shoulder 100 is withdrawn. The front disc, which is weighted for the purpose, falls back to " zero " ; then as the clutch members 104 separate, the disc 93 is drawn away from the end of the rod 88, and is reunited by the friction washer 95a to the disc 95 ; the two discs may now be rotated until the amount required is visible through window 96. On releasing knob 102 the disc 93 presses back rod 88 since its notch 92 is no longer in register ; the other end 89 is thereby released from the disc 86 and the shaft free for rotation from the pumping mechanism until by means of the spur-gearing 106, 107, 108, the notch 92 is again in alignment with the rod 88.
